Chip-breaker for flaming-machines

JOHN CONNELL, OF ROCHESTER, NEV YORK.

CHIP-BREAKER FOR PLANlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 405,014, dated June 11, 1889.

Application filed June 11, 1887. Serial 110,240,994. (No model.)

To all whom it may concern: In a chip-breaker constructed as above de- 55 Be it known that I, JOHN CONNELL, of Rochester, Monroe county, New York, have invented certain new and useful Improvements in Chip-Breakers for Planing-Machines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain improvements in the form of chip-breakers, whereby the discharge of the chips from about the cutter-head is facilitated.

My invention is fully described and illustrated in the following specification and accompanying drawings, the novel features thereof being specified in the claims annexed to the said specification.

My improved chip-breaker is illustrated in the accompanying drawings, in which Figure 1 is an elevation. Fig. 2 is a plan view. Fig. 3 is a section through the chipbreaker on the line a: m, Fig. 2.

In the accompanying drawings, representing my improved chip-breaker, A represents a portion of the frame of a planer, to which is bolted the bracket B, carrying a box 0, in which the shaft D of the cutter-head is journaled. The cutter-head, which may be of any ordinary or preferred form, is mounted on the shaft D above the bracket 13, and is driven by a belt on the pulley E. On the upper surface of the bracket B is pivoted the chip-breaker F, which is free to move laterally, but is pressed against the work J (shown in dotted lines) by the spring G. A suitable stop may be provided to prevent the chipbreaker from moving too far out, so as to hold the work away from the cutter-head. The chip-breaker partially surrounds the cutterhead, its end being formed into a lip L, to which is secured a removable plate 0, that operates in the usual manner to break the chips cut from the work and prevent their clogging the knives. The sides of the chipbreaker are cut away, as represented at N, so as to present an upward and outward incline from the face of the knives, so that as the chips are thrown outward by centrifugal force from the cutter-head they strike the inclined inner surface of the breaker and are deflected upward into the mouth of the usual exhaust or suction pipe H, which covers the upper portion of the device, and are carried off.

scribed, with an inner surface inclined so as to deflect the flying chips into the mouth of an exhaust-pipe, the motion of the cutter assists in carrying the chips into the exhaustpipe, and large pieces will therefore be carried away, instead of littering the fioor of the room in which the machine is operating, as is the case with planers provided with the ordinary chip-breaker.

I claim 1. The combination, with a cutter-head, of a chip-breaker arranged in proximity thereto, having the surface next the head, against which the chips first strike, inclined to the plane of the axis of the cutter-head, as set forth.

2. The combination, with acutter-head, of a chip-breaker partially encircling it, having the surface next the head, against which the chips first strike, inclined to the plane of the axis of the head, substantially as described.

3. The combination, with a vertical cutterhead, of a chip-breaker partially encircling it, having the inner surface, against which the chips first strike, inclined to the plane of the axis of the head, and a hood connected with an exhaust-fan arranged over the cutterhead, substantially as described.

4. The combination, with a rotating cutterhead, of the pivoted chip-breaker E, having the lip L acting on the material to break the chip, and the surface N, against which the chips first strike, inclined to the plane of the axis of the head, substantially as described.

5. The combination, with a rotating cutterhead, of the pivoted chip-breaker F, having the lip L operating on the surface of the material to break the chips, and the inner surface N, against which the chips first strike, inclined to the plane of the axis of the head, substantially as described.

6. The combination,with a rotating cutterhead, of a surface arranged -in proximity thereto, against which the chips first strike, inclined to the plane of the axis of the cutterhead, substantially as described.

JOHN CONNELL.
